GLOBE-SUPPORT.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed Aprill, 1913. Serial No. 761,605.

To all whom t may concern Be it known that I, FREDERIK VAN GEL- DEREN, a subject of the Queen of the Netherlands, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Globe-Supports, of which the following is a specication.

This invention relates particularly to globe-supporting devices adapted for use in connection with lamps having depending globes.

The primary object of the invention is to provide a simple and easily manipulated globe-supporting device, which is adapted to securely clamp and holdV a globe.

The invention is illustrated, in its preferred embodiment, in the accompanying drawing, in which Figure 1 represents an elevation of a gaslamp provided with a globe secured to the body of the lamp by means of the improved device; Fig. 2, a plan view of a rotary or oscillatory clamping-member actuator and the mounting therefor, the upper member of the mounting being removed however; Fig. 3, a plan view of the upper member of the mounting referred to and the globe-clamping members pivotally connected therewith; Fig. 4, a bottom view of the same, both Figs. 3 and 4 showing the globe-clamping members in the eccentric or clamping position; Fig. 5, an upper perspective view of one of the segmental globe-clamping members employed; Fig. (3, an enlarged broken sectional view of the globe-holder, this view showing a fragment of the globe, the section being taken as indicated at line 6, of Fig. 3; Fig. 7, an enlarged inner broken elevational view taken as indicated at line 7 of Fig. 3; and Fig. 8, an enlarged broken sectional view taken as indicated at line 8 of Fig. 2.

In the construction illustrated, A represents a lamp-body; B, a depending globe; and C, the improved globe-holder, which serves to support the globe B, and which is itself supported on the flange 1 at the lower portion of the body of the lamp.

The lamp illustrated is of the down burner type and fitted with the usual depending mantle 2, which is shielded from direct currents of air admitted through openings 8 by a shield 4.

The improved globe-support C comprises an annular mounting 5 carried by the flange l; an annular oscillatory-actuating member 6 confined in the Vannular channel with which the mounting 5 is provided; rand a plurality of segmental globe-clamping 1nembers 7, 7a and 7b. The mounting 5 comprises an o-uter ringl 8 andan inner ring 9 secured to the flange 1 by screws 10, the flange 1 being confined between the vertical portions of the members 8 and 9. The members 8 and 9 are provided, respectively, with inturned ianges 8"L and 9a. The actuating member 6 is of annular form and of angular cross-section, having a depending iange 6 and an inturned flange 6b.' The depending flange 6a is confined within the vertical wall of the member 8 and rests on the inturned flange 8a. The flange 6a is equipped ,with a stud 11 which is threaded and pro jects through a segmental slot 12fwith which the member 8 is provided in its vertical wall, the stud l1 being threaded and equipped with a clamping nut 11a, which serves as a handle for turning the annular actuating member G, and also as a means for fixing the actuating member in a set osition. The inturned flange 6b is provic ed with slots Gc, which receive the down-turned ends 18 of the segmental clamping members. The clamping members 7, 7a and 7b have their other ends connected, by pivots 14, 14a and 14", respectively, with the inturned flange 9a of the inner mounting member 9. The intermediate portions of the clamping members are equipped with upwardly and outwardly curved globe-engaging projections 15, which serve to engage the upper flange or bead of the globe.

The globe-clamping members are shown as three in number, and each member preferably overlaps somewhat with the two adjacent members. Any desired number of clamping members may be employed, however. The position of the clamping-members shown in Figs. 3 and 4, corresponds with the position shown in Figs. 1 and 2. That is, the clamping-members are shown in the globe-engaging position. In this position, the nut 11a is turned to clamp the actuating-ring G to the member 8. Vhen it is desired to remove the globe, the nut is loosened slightly, and the stud 11 is moved to the opposite end of the slot 12, in which movement the member 6, by reason of the stud-and-slot engagement between the clamping-members and the member 6, causes the izo clamping-members to swing outwardly about the pivots lll, 14:a and 14h, so that the clamping-members will assume approximately a concentric position with relation to the mounting 5, thereby releasing the globe. The mounting 5 is formed separately from the flange l of the lamp-body only by preference and for convenience of manufacture.

The improved globe-support can be manufactured at moderate cost, is readily manipulated, and does not detract from the appearance of the lamp.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitation should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.

vWhat I regard as new and desire to secure by Letters Patent isr l. A globe'support comprising an annular actuating member, segmental globe-err gaging members connected. therewith, and a mounting comprising an outer member hav ing an inturned flange and an inner member having an inturned flange disposed some distance above said first-named flange, said actuating member located between said flanges and said globe-engaging members having connections with one of said flanges, a stud carried by said actuating member and projecting through a slot in said outer member, and a nut on said stud serving as a handle and as a securing device.

2. The combination with a lamp-body pro vided at its lower portion with a flange, of a globe-support comprising an annular mounting consisting of an inner annular member and an outer annulaimember of angular cross-section, the vertical flanges of which are connected with said first-named flange and the horizontal flanges of which are in turned and separated by a space, an oscillatory-actuating member confined be tween said flanges and equipped with an actuating stud projecting through a slot in the wall of said outer member, and segmental globe-engaging members pivotally connected with the inner member of said mounting and having operative engagement with said oscillatory actuating member.

3. A globe-support. comprising an annular mounting having inturned upper and lower flanges, an annular actuating member disposed between said flanges and provided with a series of slots, and segmental globeengaging members pivotally connected with the upper flange at one end and having pro jections at the other end engaging said slots of said actuating member.
